Proto-city is a term usually used to describe large villages or towns of the Neolithic such as Jericho and Çatalhöyük, but also any prehistoric settlement which has both rural and urban features, in an attempt to distinguish them from cities in later periods. Prehistoric Egypt and the Ubaid period of Sumer featured what some call proto-cities. The break from these later mentioned settlements and urban settlements is the emergence of Eridu, the first Sumerian city, in the Uruk period around 4000 BC. A European example of this would be the Cucuteni-Trypillian culture, which dates back to the fourth millennium BC. A proto-city is distinguished from a true city in that it lacks planning, centralized rule , and in some cases, a class system . For example, Jericho evidently had a class system, but no roads, while Çatalhöyük apparently lacked social stratification.
